The neutron-deficient nucleus 123La was studied via the 92Mo(40Ca,2ap) reaction at a beam energy of 184 MeV. Previously known bands were extended to a much higher spin, and in two cases the structures are now observed near 40ℏ. In addition, three new sequences were identified and linked into previously known bands. The lowest (π,α)=(+,-1/2) structure displays characteristics similar to those of analogous bands in 127,129La, which have been proposed as examples of smooth band termination. Cranked Nilsson-Strutinsky calculations were compared with the experimental data in 123La to determine whether this band is approaching a terminating state as well
